A device and method for delivering a device such as a sensor or fluid transport structure or a fluid transport structure sensor combination into, for example, mammalian skin. Such a device allows a sensor to penetrate mammalian skin without the use of an introducer device such as a needle. A device in accordance with embodiments of the present disclosure includes a housing for attachment to mammalian skin including an exit port for receiving the distal end of a biosensor and an injection activation device including a mechanism for forcing the sensing device from a first position within the housing, through the exit port to a second position, with sufficiently high velocity to partially penetrate the mammalian skin.

Method and apparatus for insertion of a sensor

Glucagon formulations that resist fibril formation are disclosed. The formulations comprise curcumin derivatives such as ferulic acid and/or tetrahydrocurcumin and can further comprise human serum albumin, polysorbate-80, and L-methionine.

Formulations comprising glucagon

A device, system, and method for delivering a device such as a sensor or fluid transport structure or a fluid transport structure sensor combination into, for example, mammalian skin and receiving, analyzing, and displaying signals from the device such as a sensor are disclosed. A system in accordance with embodiments of the present invention includes a reusable sensor assembly including a transmitter, microcontroller, and housing plus a disposable sensor assembly including a housing having an opening for receiving both the distal end of a biosensor, a sensor insertion guidance structure, and a transmission apparatus for transmitting signals received from the sensor to a reusable sensor assembly for transmission to an external electronic monitoring unit.

Resposable biosensor assembly and method of sensing

Stabilized glucagon solutions, methods of storing and using the stabilized glucagon solutions, and drug delivery devices containing the stabilized glucagon solutions. In some embodiments, the glucagon solutions may be alkaline, such as with a pH of at least about 9. The glucagon solutions may be resistant to aggregation of glucagon when the solutions are stored for a prolonged period, such as at least about three days, at room temperature and/or physiological temperature.

Stabilized glucagon solutions and uses therefor

Embodiments provide a method and related systems that take into account the difference between a measured glucose value and the calibration level and the amount of elapsed time since the prior calibration. As one or both of these determined differences increases, the desirability of an additional calibration also increases. The methodology described herein thus analyzes the combination of change in glucose level as well as the time since the prior calibration. If the combination exceeds a predetermined value, the system recommends, but does not require, that the subject user perform an additional calibration.

Additional calibration for analyte monitor

A sensing element adapted to, at least in part, be inserted into a mammalian body. The sensing element is made up of a core of a structurally robust metal and a plated portion made of an electrochemically active metal conjoined to at least a portion of the core. This sensing element may be used as part of a method for the continuous or intermittent monitoring of an analyte within a mammalian body. The method includes inserting at least a portion of the sensing element into the mammalian body and measuring any electric current produced by at least of portion of the sensor.

Compound material analyte sensor

Electrochemical systems for measuring an analyte concentration, and correcting any surplus or deficiency in the measured concentration. More specifically, systems for measuring an analyte level in a fluid with an implantable sensor, processing the measurements with an algorithm, and determining an appropriate fluid infusion rate in response to the measurements.

Analyte sensing and response system

A method of measuring an analyte concentration in body fluid. The method includes the use of an analyte measuring device that has an analyte sensing element with a sharpened distal end and further has an indicating electrode covered by an absorbent layer. Also, an electric power, data processing and display device is adapted to mate to and activate the analyte sensing element by applying electric power to it and adapted to receive the raw analyte measurement and to compute and display a refined analyte measurement from the raw analyte measurement. The analyte sensing element is introduced into the animal body, thereby placing the absorbent layer into contact with the body fluid. The absorbent layer becomes saturated with body fluid and the analyte sensing element is removed from the body and is activated to form a raw analyte measurement. Whichwhichis used to form and display a refined analyte measurement.

Methods for analyte sensing and measurement

Embodiments of the present invention provide methods, apparatuses, and systems associated with detecting, analyzing, and/or displaying historical glucose levels and/or trends in a body.

Method and apparatus for managing glucose control

Embodiments of the present invention improve the accuracy of measurements and/or in vivo calibrations of a biosensor by (1) using more than one sensor signal value and/or more than one directly sampled and measured value, such as a capillary blood glucose value, and/or by (2) delaying the acquisition of a sensor output value that is compared with a directly sampled and measured value, such as a capillary blood glucose value, during a calibration. In an embodiment of the present invention, the median of a series of measured values, or a median or mean of the medians, may be utilized to provide more consistent and accurate measurement data and/or to compensate for error or artifact.

Use of multiple data points and filtering in an analyte sensor

Embodiments of the present invention provide for raising a background current setting for a biosensor above the actual (measured) background current present (i.e., overestimating the background current), particularly in the hypoglycemic range, to improve sensor accuracy and decrease the chance of glucose value overestimation by the sensor.

Method and apparatus for background current arrangements for a biosensor

A multiple use analyte sensing assembly that includes a long, thin conductor. A plurality of sensing sites are spaced along the conductor and each sensing site includes a membrane system adapted to create a current when placed into contact with body fluid containing the analyte. The assembly also includes a housing, having an aperture, an uptake spool and a payout spool, the conductor being wrapped about the payout spool before the sensing assembly is used. A sensor positioning actuator turns the uptake spool to move each sensing site, in sequence, to the housing aperture and then to the uptake spool. The assembly also includes a skin broaching assembly, having a multiplicity of lancets and a lancet positioning actuator adapted to move each lancet to the aperture. In addition, a lancet use actuator is adapted to move each lancet at least partially through the aperture and then back again.
